<h2>DESCRIPTION</h2>

<em>i.eb.evapfr</em> calculates the evaporative fraction after
Bastiaanssen 1995. The main implementation follows Alexandridis et al.
(2009). The module takes as input the net radiation (see <em>r.sun</em>,
<em>i.eb.netrad</em>), soil heat flux (see <em>i.eb.soilheatflux</em>)
and sensible heat flux (see <em>i.eb.hsebal01</em>). A flag adds a
root zone empirical soil moisture output from the article of
Bastiaanssen, et al. (2000).
